Rework a section

Use the client from request setup. These examples assume api, userAddress, and the returned songId are available. api includes the session token and selected account headers. Choose a positive interval in seconds that fits the source. This example changes seconds 15 through 30:

const job = await api.post('/api/editing/apply', {
  songId, userAddress, task: 'repaint',
  repaintingStart: 15, repaintingEnd: 30,
  prompt: 'Sparse drums and a warmer bass',
  repaintMode: 'balanced', repaintStrength: 0.5,
  modelQuality: 'sft',
});

conservative, balanced and aggressive describe repaint intent. repaintStrength ranges from 0 to 1. You can request transition length through repaintWavCrossfadeSec and latent transition frames through repaintLatentCrossfadeFrames. Listen to the boundary; these are model controls, not guarantees of a precise audible crossfade. For vocal changes, include lyrics. /apply also accepts seed, BPM, key and language. The shortcut /repaint uses start and end instead of repaintingStart and repaintingEnd. Use the polling function from job handling.

// Save job before polling so your product can resume after a reload.
const path = `/api/editing/status/${encodeURIComponent(job.taskId)}?` +
  new URLSearchParams({
    songId: job.songId, userAddress, task: job.task,
    ...(job.stemId ? { stemId: job.stemId } : {}),
  });
const result = await pollJob(() => api.get(path));

Keep the returned taskId, songId, task, and optional stemId. A polling timeout stops your client from waiting; it does not cancel the job. The ready result is an inactive candidate. Preview result.audioUrl, then activate or merge its take. The unchanged source remains available until you keep a result.
